    Publication number: 20190149291
    Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. A channel state information (CSI) report may include a CSI part 1 transmission and may be configurable to include a CSI part 2 transmission. The UE may determine a first number of coded modulation symbols per layer to be used for the CSI part 1 transmission on a physical uplink shared channel (PUSCH) without uplink shared channel (UL-SCH) data. The first number of coded modulation symbols per layer may be determined as: a minimum of a first term and a second term if the CSI report includes the CSI part 2 transmission; and the second term if the CSI report does not include the CSI part 2 transmission.

  • METHODS OF LIMITED BUFFER RATE-MATCHING (LBRM), PRE-EMPTION, AND SIDELINK SYNCRHONIZATION IN NEW RADIO (NR) SYSTEMS
    Publication number: 20190141647
    Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

  • BEAM MANAGEMENT FOR DUAL TRANSMISSION POINT HYBRID BEAMFORMING SYSTEMS IN 5G
    Publication number: 20190089435
    Abstract: Devices and methods of beamforming are generally described. A UE transmits to an eNB a BRSRP report having selected BRSRP values and associated BRS IDs. An active link list, a CSI resource indication, and a first active link are used to measure the CSI resource and CSI feedback is sent. A serving link ID is provided to indicate a second active link to use for control and data reception. Rx beams are trained based on multiple instances of each BRS and the eNB supplies selection criteria for the BRSRP report. The Rx beams are refined based on BRRS and the second active link is dependent on BRRSRP or CSI feedback. When configured for dual beam operation, the BRSRP feedback corresponds to BRSRP value pairs and dual Rx beams associated with a pair of serving link IDs are used.
